FinTech Lead – Nairobi

M-HOOK

Every day a fintech loses thousands of dollars to fraud that could have been stopped seconds after it starts.

M-PROBLEM

African fintechs face rising fraud rates as digital payments expand. Rule‑based systems generate many false positives and miss sophisticated attacks, leading to revenue loss and eroded trust.

M-CONTEXT

In Lagos, a mobile money provider saw fraud‑related losses climb to 1.8 billion NGN in 2023, according to GSMA data. Across the continent, the World Bank estimates that digital fraud costs African economies over 2 billion USD annually, undermining financial inclusion efforts.

GSMA and World Bank provide the underlying statistics.

M-HOWWORKS

NeuroptikAI’s fraud engine ingests transaction streams, device fingerprints, and behavioural signals from USSD and app APIs. A hybrid isolation forest and gradient boosted model scores each transaction for anomaly likelihood within milliseconds, flagging high‑risk events for immediate review.

The model retrains every six hours using the latest labelled data, adapting to new fraud patterns while maintaining low false‑positive rates.

M-CASESTUDY

The following example illustrates typical results NeuroptikAI achieves for clients in this sector.

Client: A fintech provider in Nairobi, Kenya

Challenge: 12 % of transaction volume flagged as suspicious, causing high manual review costs.

Solution: NeuroptikAI designed and implemented a custom AI fraud detection system that integrated with the client’s payment gateway and mobile money APIs.

35% – reduction in fraudulent transaction value.
$900K – quarterly revenue protected from fraud loss.
30% – decrease in manual review hours required.

M-MYTHS

MYTH 1

AI fraud detection is too expensive for small fintechs

Cost is spread across transaction volume; custom deployment avoids costly third‑party licences and scales with usage.

MYTH 2

Data privacy rules block AI models

All models operate on tokenised, anonymised data and comply with Kenya’s Data Protection Act and GDPR‑style frameworks.
